that manifold is fine. its welded from the inside on the exhaust flange and the turbo flange. you just have to brace it right, example: if you have a crx, i'm sure you could brace it to the cross member.

I got a t3a4, its actually a T3..slightly smaller, it uses a t3 manifold, and a 4 bolt downpipe (i got the flange, and feed and drain fittings as well). If your interested I'll check the specs for you, it's used but freshly rebuilt..No shaft play. 150+shipping
